Problems solved by technology

[0003] In the traditional smart meter, the external wiring is introduced into the housing of the electric energy meter through the terminal. In actual use, the connection between the external wiring and the terminal is prone to loosening, resulting in poor contact or easy to fall off when the external wiring is accidentally or maliciously pulled. Or slack, causing the energy meter to not work properly

Abstract

The invention relates to the field of smart electric meters, in particular to a DC smart electric energy meter. The terminal is connected with an external wire which passes through the anti-pull mechanism and is externally inserted into the housing. In the present invention, an anti-pull mechanism is provided below the terminal, the anti-pull mechanism includes a bar block, a plurality of sets of wire winding rollers symmetrically distributed up and down, a sliding block connected to the wire winding roller, a spring between the sliding blocks, and a penetrating sliding block. The guide bolt of the block makes when the external wire is pulled, the winding rollers are close to each other and the external wire is pulled to provide a buffer buffer. The wire roller squeezes and locks the external wiring, improves the anti-pulling ability, maintains the contact between the external wiring and the terminal, and has a good anti-pulling effect.

Description

technical field [0001] The invention relates to the field of smart electric meters, in particular to a DC smart electric energy meter. Background technique [0002] Smart meter is one of the basic equipment for data collection in smart grid (especially smart distribution network). In addition to the basic electricity metering function of traditional energy meters, smart meters also have two-way multi-rate metering functions, user-side control functions, and two-way data communication with multiple data transmission modes in order to adapt to the use of smart grids and new energy sources. Intelligent functions such as function, anti-theft function and so on. [0003] In the traditional smart meter, the external wiring is introduced into the housing of the power meter through the terminal. In actual use, the connection between the external wiring and the terminal is prone to loosening, resulting in poor contact or falling off when the external wiring is accidentally or malici...
